Does Iceland have lava flows?
Iceland is located on a hot spot or mantle plume, where magma is especially close to the surface, which explains why land formed in this spot in the middle of the ocean, and not elsewhere along the tectonic ridge. Since the Middle Ages, a third of all lava that has covered the earth’s surface has erupted in Iceland.
What method was used on the Icelandic island of Heimaey to deflect the lava flow?
Efforts to halt the lava by spraying water onto its front failed due to the high mobility of this flow. Following the late March surge of lava effusion into the town, cooling of the lava by spraying sea water onto it was performed at ever increasing scale.
How did Iceland stop lava flow?
An operation was mounted to cool the advancing lava flow by pumping sea water onto it, which was successful in preventing the loss of the harbour. After the eruption, the islanders used heat from the cooling lava flows to provide hot water and to generate electricity.

The fissure extends in a straight line and trends in a direction NNE-SSW. It extends into the sea at both ends, and small islands seem to be forming near the coast under the sea as lava continues to extrude from the fissure. Fire and pyroclastic clouds are visible, and the lava fountains reached 375 feet in height.
